What Is a Healthy Diet? The Answers Are Unsatisfying | Retro Report



is America the land of a heavy we should eat less meat we should eat less fat the hefty West beat eggs junk foods the large the Rollie pollie most Americans must lower their cholesterol whatever it takes the chunky eat oat bran in other words is merica too fat after nearly 40 years of advice about what to eat and how to exercise millions of Americans are getting fatter and that's not all you have these massive increased obesity and diabetes that coincide with this epidemic of nutritional advice we've been giving and the role our diets play is as confusing and controversial as ever more protein or me it's okay to eat butter again leaving us once again with the question what should we eat for dinner a stunned nation hears that its president is stricken with a heart attack the chief executive is rushed to Fitzsimmons Hospital where he is immediately placed in an oxygen tent President Eisenhower was a very good example of what was happening with middle-aged men the president had been stricken by the greatest Mankiller heart disease in the 1950s and 60s Americans were having heart attacks at an alarming rate our disease is an epidemic the average American male reaching adulthood have one chance in five of having heart disease before age 60 that's a very high risk and top researchers like dr. Jeremiah Stemler thought they knew a big reason why a diet high in saturated fat and cholesterol the nutrition committee was told that Americans are eating themselves to death eating too much of the wrong food Jeremiah but many researchers complain that the science was too controversial to recommend major changes in diet eight studies involving 5,000 patients failed to show hard medical evidence that diet has anything to do with heart attacks some of the best scientists had looked it's a very controversial subject it's a very complicated subject you can't just tell people to reduce the amount of fat in their diet because diet is a trade-off if we reduce the amount of fat you have to replace it with something I have pleaded in my report and will plead again orally here for more research on the problem before we make announcements to the American public well I would only argue that senators don't have the luxury that a research scientist does are waiting until every last shred evidence is in definitive studies could take years and cost hundreds of millions of dollars and in 1980 the government issued the first Dietary Guidelines which called for cutting back on a variety of nutrients including fat and cholesterol the physicians perspective was look you've got people who are sick and dying we have pretty good evidence that dietary fat is the problem we don't have time to dot the i's and cross the t's we were reasonably secure that these recommendations were not being harmful the issue appeared to be put to rest four years later with a landmark study that showed that lowering cholesterol reduced the risk of heart attacks but there was one problem the study also used cholesterol-lowering drugs and the scientists assumed that a low cholesterol diet could work as well when I interviewed the administrator oversaw the trial he said to me look we confirmed a lowering cholesterol at least by drugs seems to reduce heart disease risk and we took a leap of faith scientists now have conclusive proof that lowering the amount of cholesterol or fat that we eat can significantly reduce the chance of heart attacks cutting all fat and cholesterol became a national obsession cholesterol could be building up in your arteries cholesterol is now thought to be a danger for everyone even children once they passed their second birthday should try to reduce fat in their diet by 25% and cholesterol by 30% or more than just if it was that if a food didn't have fat in it it couldn't make you fat bread pasta potatoes rice now become the base of the food guide we should eat more of the foods at the bottom of the pyramid like bread and cereal and less of the foods at the top all of the food companies think AHA now we have to talk about how our product cuts back on fat no you're watching your cholesterol you can still bring out the best there was a whole line of snack Wells which had no fat whatsoever snack was was a very successful product because it was on the no fad craze low-fat dissenters like Robert Atkins who said to eat meat and cheese while avoiding carbohydrates were branded as heretics the idea was if you told people to eat fat and saturated fat you were going to kill them telling people that pork rinds and sausage is good for you is an appealing way to sell books but I think it's irresponsible it was the equivalent of committing mass murder but even as Americans were cutting down on fat a new health problem was emerging Americans are fatter than ever before obesity is a major risk factor for heart disease heart attacks there is an alarming report today about an increase in diabetes it really turned on almost like a switch in 1980 obesity was stable for many decades so what changed in 1980 we put the whole country on a low-fat diet and lo and behold we have an obesity epidemic and that's what started my research science journalist Gary Taubes and doctors like Daria Schmo safari n' soon began to question the conventional wisdom I started reading myself about the dietary guidelines I'm starting to look into the evidence and I was stunned I was stunned to find that about 90% of the dietary guidelines were basically best guesses there was a small and growing minority of researchers who were coming to believe that the problem and modern diets for the sugar and there were fine grains and not the fat if the American Medical Association had a nightmare it was the possibility that Atkins was right all along it is one of the hottest battles and like health today high-carb versus – a landmark study a 49th the evidence started accumulating that there's really no association at all between total fat intake and heart disease or stroke the results might surprise you consuming less fat did not reduce the risk of cardiovascular disease and cancer and many foods made to capitalize on the low-fat craze had their own drawbacks if you looked at the calorie content that was all high calorie lots of carbs if you take out the fat a person's gonna eat more because there aren't any signals I'm full full full we had an explosion of high carbohydrate sugary foods and those have contributed to the obesity epidemic obesity is growing faster than any other public health problem in US history this is a law of unintended consequences you just don't know what's gonna happen when you make your recommendation you're putting it affect the American public on it this grand experiment you have no idea how it's going to work out dr. Stambler says his recommendations were misinterpreted those of us for recommending or recommending vegetables fruits and not special desserts now facing an obesity epidemic the public continued to be inundated with nutrition studies and diet advice the raw food diet eat more butter meat and cheese don't eat sugar what would Jesus eat and Taub says one of the main sources of confusion is conflicting and inadequate diet science past studies have rarely been large enough long enough or the diets different enough to provide definitive answers if you search obesity and/or diabetes you can pick and choose your research and say look we should all be eating a vegan diet or we should all be eating a ketogenic diet or a fruitarian diet or you know you pick it you can find research to support it it's a huge problem with nutrition in 2012 Taub's co-founded the nutrition science initiative to fund new more rigorous studies and try to find out not just what foods to avoid but what we should really be eating instead everyone agrees for the most part now that we shouldn't be eating a lot of sugar and white flour and then the question is what do you replace those calories with professor Christopher Gardner who's leading one of the studies is finding that the answer may be different for different people there's this massive variability in response to the same diet we had some women losing 60 pounds and some losing 0 so maybe it was the wrong question which diet is best maybe the better question was is there a way to match different people to a diet that they're more predisposed to with the answer still unclear Moe's affari and worries that the conventional wisdom is being oversimplified again from low-fat to just cut carbs and calories we made a mistake focusing on just total fat and I think we're in danger of making the same mistake now now we have a public health crisis of obesity and diabetes and so everybody's trying to do something a new government rule requiring big restaurant chains to post their calorie counts the major focus now has been on calories just cut calories portion size control smaller portion of french fries there are foods that have more calories that are good for us that are good for obesity and diabetes and there are foods that have fewer calories that are bad it's not just about fat and it's not just about calories it's about the quality of the food that you eat we have to stop thinking about single targets as though just focusing on one thing will give us the answer here we go again experts are changing their recommendations about what we shouldn't eat the Dietary Guidelines Advisory Committee now considers taking cholesterol off the list of things we should avoid in 2015 a scientific advisory panel revisiting the Dietary Guidelines said there is actually little evidence that high cholesterol foods lead to high cholesterol in our blood cholesterol is still linked to heart disease but what we've learned is the cholesterol in our blood most of it doesn't come from food our body makes it on our own and when the new guidelines were released in January 2016 they did away with the cholesterol limits but still recommended cutting back on foods that are high in both saturated fat and cholesterol among the recommendations limit your intake of added sugars often found in beverages and processed foods and saturated fats to 10% of your daily calories some experts were disappointed that the guidelines didn't adopt all the recommendations of the Advisory Committee the guidelines could have a big impact at a time when more than 2/3 of Americans are overweight or obese meanwhile moseph Arion says nutrition science has come a long way since the 1980s as advances have led to a better understanding of the importance of Whole Foods and eating patterns and he says we're still learning the lessons of the past I think now we know about 50% of what we need to know and we need to be a little bit more modest and not said strong guidelines for areas that we're still not certain about we have to get the science right you

  1. What ever happened to moderation in diet? Eat what you want, but don't go crazy on one thing. Green leafy veggies are pretty much the only thing you can eat however much you want without adverse effects.

  2. Very cogent.

  3. YESH! My favorite online series 😀

  4. Holy vocal fry!
